The NACC/WG is the only regional implementation mechanism in the region, integrating all the Task Forces of the different air navigation areas and it is the mechanism through which the region reports its level of implementation.   

The NACC/WG integrates the Task Forces in the fields of Aeronautical Information Management (AIM), Air Traffic Management (ATM), Communications, Navigation and Surveillance (CNS), and the joint tasks with the areas of Aerodromes and Ground Aids (AGA) and Meteorology (MET). Additionally, it integrates joint work on cybersecurity for air navigation and unmanned aircraft operations.

The different Task Forces lead the specific tasks of their areas, and through the Group of Rapporteurs that integrate the different Task Forces, discussions are held, and decisions are made on the air navigation implementation and improvements at the regional level.

The NACC/WG is the mechanism which reports to the CAR/SAM Regional Planning and Execution Group (GREPECAS), that is the Regional Planning and Execution Group (PIRG), which reports to the Air Navigation Commission.
